Range.
Referring to Fig. 1, a kind of air-conditioning system in the embodiment of the present invention, comprising: compressor 1, four-way valve 2, outdoor heat exchanger
3, the first indoor heat exchanger 5, the second indoor heat exchanger 7 and dehumidify magnetic valve 10；
The compressor 1 is connect by four-way valve 2 with the outdoor heat exchanger 3, the outdoor heat exchanger 3 successively with first interior
Heat exchanger 5, the connection of the second indoor heat exchanger 7, second indoor heat exchanger 7 are connect by the four-way valve 2 with the compressor 1；
The dehumidify magnetic valve 10 is installed in parallel with the outdoor heat exchanger 3, and one end is connect with the four-way valve 2, the other end with should
The connection of first indoor heat exchanger 5.
Preferably, first is additionally provided in the connecting pipe between first indoor heat exchanger 5 and the second indoor heat exchanger 7
Throttle valve 6, the first throttle valve 6 are preferably electric expansion valve, can be to the refrigerant expenditure and pressure passed through.
Preferably, the second section is additionally provided on the interface channel between the outdoor heat exchanger 3 and first indoor heat exchanger 5
Valve 4 is flowed, which is arranged on the pipeline in parallel with 10 place lateral of the dehumidify magnetic valve.Particularly, this
The characteristics of two throttle valves 4 can be electric expansion valve, and electric expansion valve has function admirable, is convenient for control.
Preferably, the air-conditioning system further includes hydrojet solenoid valve and plate heat exchanger, board-like is changed as shown in Figure 1, described
One end of hot device is connect with the compressor, and the other end is connect with the hydrojet solenoid valve, one end of the hydrojet solenoid valve with
The plate heat exchanger connection, the other end are connect with first indoor heat exchanger.
Preferably, the blower of rotation rate-controllable is provided on the outdoor heat exchanger 3.
The working principle of the air-conditioning system is as follows in the present embodiment:
When refrigeration: refrigerant is compressed into the gas of high temperature and pressure by compressor 1, after four-way valve 2, reaches outdoor heat exchange
Device 3 is cooling (at this point, dehumidify magnetic valve 10 is closed), becomes the gas-liquid mixture of high normal pressure and temperature.Then, which passes through
Become the gas-liquid mixture of low-temp low-pressure after second throttle 4, then passes through the first indoor heat exchanger 5, first throttle valve 6 and second
Indoor heat exchanger 7 (at this point, 6 standard-sized sheet of first throttle valve, hydrojet solenoid valve 8 is closed) heat exchange evaporation becomes overheated gas, from four-way
Valve 2 is back in compressor 1, forms refrigeration cycle.
When heating: refrigerant is compressed into the gas of high temperature and pressure by compressor 1, after four-way valve 2, successively reaches second
(at this point, 6 standard-sized sheet of first throttle valve, hydrojet solenoid valve 8 is closed for indoor heat exchanger 7, first throttle valve 6 and the first indoor heat exchanger 5
Close) heat exchange cooling, become the gas-liquid mixture of high normal pressure and temperature, then the gas-liquid by becoming low-temp low-pressure after second throttle 4 is mixed
Object is closed, then becomes returning in compressor 1 from four-way valve 2 (at this point, dehumidifying electromagnetism after overheated gas by the evaporation of outdoor heat exchanger 3
Valve 10 is closed), form heating circulation.
Particularly, when low-temperature heating: when external environment temperature is lower, the heat exchange amount of outdoor heat exchanger 3 is few, is easy to cause back
Tolerance is few.Therefore plate heat exchanger 9 and hydrojet solenoid valve 8 are opened, dehumidify magnetic valve 10 and second throttle 4 are closed.Refrigerant
It is compressed into the gas of high temperature and pressure by compressor 1, after four-way valve 2, successively reaches the second indoor heat exchanger 7, first throttle
Valve 6 and the heat exchange cooling of the first indoor heat exchanger 5, become the gas-liquid mixture of high normal pressure and temperature, then pass through hydrojet solenoid valve 8 and plate
Become overheated gas after formula heat exchanger 9, finally return in compressor 1, forms low temperature spray liquid enthalpy gain system circulation, effectively improve
Heating capacity under low temperature environment.
When dehumidifying: when room temperature is less than set temperature, dehumidify magnetic valve 10 is opened, and refrigerant is compressed by compressor 1
At the gas of high temperature and pressure, after four-way valve 2, dehumidify magnetic valve 10 is reached (at this point, hydrojet solenoid valve 8 and second throttle 4
Close), then by the cooling gas-liquid mixture for becoming high normal pressure and temperature of the first indoor heat exchanger 5, then by after first throttle valve 6
Become the gas-liquid mixture of low-temp low-pressure, then overheated gas is become by the evaporation of the second indoor heat exchanger 7 and returns to pressure from four-way valve 2
In contracting machine 1, desiccant cooling is formed.It should be noted that in this process, it is indoor since system off heat amount is greater than row's cooling capacity
Temperature will slowly rise, and when room temperature is greater than set temperature, can open the blower of outdoor heat exchanger 3, and control blower
Revolving speed so that extra system thermal is discharged outward, room temperature is slow to be down to set temperature, to keep the perseverance of room temperature
It is fixed.

Device 5, the second indoor heat exchanger 7 and dehumidify magnetic valve 10；The compressor 1 is connect by four-way valve 2 with the outdoor heat exchanger 3, should
Outdoor heat exchanger 3 is successively connect with first indoor heat exchanger 5, the second indoor heat exchanger 7, which passes through
The four-way valve 2 is connect with the compressor 1；The dehumidify magnetic valve 10 is installed in parallel with the outdoor heat exchanger 3.In the present embodiment,
When being dehumidified, outdoor heat exchanger 3 and dehumidify magnetic valve 10 are switched according to the variation of room temperature, dynamic adjustment first is indoor
The heat exhaust of heat exchanger 5 and the second indoor heat exchanger 7 and row's cooling capacity, to realize that room temperature is constant when dehumidifying, avoids low
The further lowering of situation of room temperature, improves the comfort level of indoor environment under the plum rain season environment of warm high humidity.
